摘要： A porous separator, to be used in electrolyzers for producing hydrogen and oxygen by water electrolysis, consists of a fabric or felt entirely made of polyphenylene sulfide (PPS). In order to reduce the voltage drop caused by the separator, the PPS polymeric chain can be made ionically active by the presence thereon of polar groups, such as sulfonic, carboxylic or phosphonic groups.The method for producing the separator comprises the preparation, according to conventional weaving or felt manufacturing techniques, of a fabric or felt entirely made of PPS and the subsequent functionalization for introducing polar groups in the polymeric chain. The functionalization can be carried out either on the starting material, such as PPS polymer powder or flakes, or in any other step of the production of fabric or felt.

摘要： A method of shaping an organic polymer insoluble in a polar solvent comprising reacting an insoluble organic polymer containing at least one Lewis acid electron attracting group or Lewis basic electron donating group with a sufficient amount of a lower alkylene oxide to alkoxylate the Lewis group and form an alkoxylated product soluble or easily dispersible in a polar solvent, dissolving or dispersing the alkoxylated product in a polar solvent, shaping the alkoxylated product into the desired form by applying the solution or dispersion to a support and removing the polar solvent, and hydrolyzing the alkoxylated product to obtain the original polymer in the desired form. Products made by the process include self-supporting polymeric films and porous diaphragms for electrolytic cells made by impregnating suitable porous supports with the alkoxylated product.
